Universal scaling limits at the spectral singularity of structured random matrices

Markus Ebke, Torben Krüger

The empirical spectral distribution of Hermitian -block random matrices converges to a deterministic density on the real line with a potential atom at the origin as the…

Planar Novikov-Shubin invariant for adjacency matrices of structured directed dense random graphs

Torben Krüger, David Renfrew

The Novikov-Shubin invariant associated to a graph provides information about the accumulation of eigenvalues of the corresponding adjacency matrix close to the origin. For a direc…

Brown measures of deformed -valued circular elements

Johannes Alt, Torben Krüger

We consider the Brown measure of , where lies in a commutative tracial von Neumann algebra and is a -valued circular e…

Spectrum occupies pseudospectrum for random matrices with diagonal deformation and variance profile

Johannes Alt, Torben Krüger

We consider non-Hermitian random matrices with independent entries and a variance profile, as well as an additive deterministic diagonal deformation. We show that their…

Local elliptic law

Johannes Alt, Torben Krüger

The empirical eigenvalue distribution of the elliptic random matrix ensemble tends to the uniform measure on an ellipse in the complex plane as its dimension tends to infinity. We…

Inhomogeneous Circular Law for Correlated Matrices

Johannes Alt, Torben Krüger

We consider non-Hermitian random matrices with general decaying correlations between their entries. For large , the empirical spectral distributi…

Cusp Universality for Random Matrices II: The Real Symmetric Case

Giorgio Cipolloni, László Erdős, Torben Krüger +1

We prove that the local eigenvalue statistics of real symmetric Wigner-type matrices near the cusp points of the eigenvalue density are universal. Together with the companion paper…

The Dyson equation with linear self-energy: spectral bands, edges and cusps

Johannes Alt, Laszlo Erdos, Torben Krüger

We study the unique solution of the Dyson equation \[ -m(z)^{-1} = z - a + S[m(z)] \] on a von Neumann algebra with the constraint . Here, $…
